Frank Bunce is in the unusual situation of being assistant coach of a province (Thames Valley) and also 2-I-C of an Auckland club side (Manukau). He has brought down one of his club charges, 136kg tighthead prop Eva Taumalolo, nephew of former Chief Sona Taumalolo. Teenage first five Josh Turner, who scored a fine solo try against the Cooks, is likely to be injected off the bench.
Bunce will get to say hello to his old All Black teammate, Steelers coach Tana Umaga, who has rewarded club form in a new-look squad minus Super Rugby players and the likes of rehabbing flanker Adam Cathcart. Counties Manukau have had runs against the Harlequins, Samoan Under-20s and North Harbour.
"We know the history of Thames Valley. We were surprised they hadn't challenged for the Shield more recently, but we are pretty close as unions," said Umaga. "There wasn't really any question as to who would get the first challenge [of 2014]."
The onus will be on players such as halfback Kane Hancy, big loose forward Maama Vaipulu and lock Ronald Raaymakers to lead the way for the home side.
Former Auckland loosie Onosa'i Auva'a will lend extra experience to the pack, while the mercurial Ahsee Tuala, normally a fullback or wing, will turn out at No10, where he has impressed for his Manurewa club.
Thames Valley have beaten Auckland and Australia, among others, in their 92-year history, but victory here, though highly unlikely, would top those feats.
